It's spring break in Rainbow Falls and true crime aficionado Annie Abbott is hoping to cater to the hoards of college kids descending on her coastal town by hosting a Gatsby-themed murder mystery party. She's hoping her twenties era whodunnit at a local historic mansion will increase tourist revenue and build her business's brand. The party is the talk of the town when a despised social media influencer is attacked and left for dead on the estate's grounds. With the help of her online friends, Annie searches for clues. The list of suspects reads like the town's social directory—but who benefits most from the victim's silence? Annie's parents are due home from their year-long adventure, so her time in Rainbow Falls is winding down. With a growing suspect list and tension among her friends, Annie worries about her own future. Should she settle in Rainbow Falls? Do she and Ben, her boyfriend and the town vet, have a future? Will she live long enough to find out?
